2. Selection of strong seedlings: Selection of grafting cuttings: the height of one-year-old seedlings is more than 1 1cm, and that of two-year-old seedlings is more than 40cm. Selection of seedlings: the height of annual seedlings is more than 25cm.
3. Reasonable close planting: design corresponding density according to site conditions, variety characteristics and tending management level. The suitable row spacing is 2.5-3.0m, and the plant spacing is 2.0-3.0m, that is, 60- 120 plants per mu.
4. Planting time: the survival rate of the forest is high in late winter and early spring, and it can be from late October to May of the following year in winter 165438. And planting in spring is better. Planting should be done on cloudy or sunny nights, but not when the soil is too wet in rainy days.
5. Daily management: weeding and loosening soil: weeding and loosening soil twice a year, the first time in May-June, the second time in August-September, 3-4 years, and then 1-2 times a year. Weeding and loosening soil should pay attention to soil and water conservation; Fertilization: Fertilization is particularly important in the first few years of afforestation. Combined with the management in intercropping crops, organic fertilizer can be added to improve the soil. In the young tree stage, vegetative growth is the main factor, nitrogen fertilizer is the main factor, combined with phosphorus and potassium fertilizer, and new shoots in spring, summer and autumn are the main factors. With the growth of tree age, the amount of fertilization will increase year by year.
